(Operations and Effects of the Invention) The squeezing device of the present invention can be implemented as described above and can be used for bag making and packaging, and according to the squeezing device of the present invention, the squeezing hole can be Since the forming movable piece group and the driving rotary ring are arranged at the same position,
Not only can the entire device be constructed very compactly, but the transmission mechanism from the rotary ring to each movable piece can also be extremely simple, consisting of a drive groove 11 and a driven pin 13, as shown in the embodiment. , the entire device can be simply configured with a small number of parts.

Furthermore, the oblique sides (
In the embodiment, the side 8a) does not move toward the center of the aperture hole, but moves tangentially to the rotating direction of the rotary ring (the circumferential direction of the aperture hole), thereby reducing the aperture hole. Therefore, the area around the opening of the bao wrapper (noodle wrapper 38 in the example) squeezed by the oblique sides of these movable pieces tends to be twisted in the circumferential direction, and the numerous folds around the opening tend to twist with the fingertips. Since the bao is squeezed in a relatively orderly folded state in substantially the same manner as when it is squeezed, it is possible to produce baozi with a beautiful surface condition at the squeezed portion and a high commercial value.
